Angle of Repose Formula
The following formula is used to calculate the angle of repose.
a = atan (h/r)
- Where a is the angle of repose
- h is the height
- r is the radius/distance
To calculate an angle of repose, take the inverse tangent of the height divided by the radius or distance.
Angle of Repose Definition
An angle of repose is a measure of the flowability of bulk solids such as powders. In other words, when bulk solids are poured into a heap or mound, what is the angle the heap makes with the ground.
Angle of Repose Example
How to calculate angle of repose?
- First, determine the height.
Measure the height of the mound or heap of solid.
- Next, determine the radius.
Measure the radius/distance of the mound.
- Finally, calculate the angle of repose.
Calculate the angle of repose using the equation above.
